How to tame and breed horses in Minecraft
Each failed try makes it calmer, food speeds things up, and two tamed horses fed Golden Carrots give you a foal.

A Golden Carrot is a carrot wrapped in gold nuggets, the most nourishing everyday food.
It is made with the Crafting Table from 8 × Gold Nugget and Carrot.
Eight gold nuggets around a Carrot make one. It restores 6 hunger points with very high saturation, so you stay full longer than with any other common food. It is also the ingredient of night vision potions and breeds horses and donkeys.
8 × Gold Nugget + Carrot → Golden Carrot
